Hiya, i am 23 and have been having unprotected sex since i was 19. I was in a long term relationship at the time and we were young and wanted a family. Now, I am greatful i didn't get pregnant then as i was still very much a child but, now 4 years later and i have still not gotten pregnant. At the beginning of the year, I was 3 & 1/2 weeks late, and thn when it did come, it was very very light and went for about9-10 days(instead of my usual 3-5). I was scared and didnt go to a doctor until a month later. Test was negative by then. Doctor said it was a spontaneous miscarriage that we'd completely missed it, but im not sure what the truth is bcos another dr. told me i was fine and it was just an irregular period. Now I am thinking i may be infertile as 4 yrs unprotected sex and still not pregnant. Can you help?
